    Abstract: A circuit for preventing power imbalance of a resonance-type power converter is proposed. The circuit may include a rectifier converting input alternating current (AC) into direct current (DC) and frequency-controlled first and second resonant converter modules configured to receive an output voltage of the rectifier divided into two stages. The circuit may further include a controller outputting a first frequency command for controlling a frequency of a pulse width modulation (PWM) signal supplied to a switching element of a first switching unit of the first resonant converter module. The circuit may further include a frequency compensator compensating for the first frequency command and then outputting a second frequency command for controlling a frequency of a PWM signal supplied to a switching element of a second switching unit of the second resonant converter module, so as to eliminate power imbalance between the first and second resonant converter modules.
